I bought one of these over priced Mothers powerball mini's to apply product to my wheels, I like it. I've been using NXT 2.0 untill my PB's wheel sealant shows up.

 

maybe I should get one.

I've been procrastinating the purchase, but detailing season is here so what the heck

 

Ive thought about getting one of those mini Flitz ***** for polishing the tunnel of my snowmobile.
Ive got a regular Flitz ball right now and its a little too big...

 

I highly reccomend the "mini" for chrome parts with gaps and small spaces. No elbow grease required and it does an EXCELLENT job of bringing the shine out. I use mine with the Mothers Paste in the jar. Great stuff, but yes, a tid bit expensive. I also have the large powerball, however, I like the mini over the other.
